IMPROVEMENT IN CORN-MARKERS.

Specification forming part of Letters Patent No. 169,177, dated October26,1875, application filed August 21, 1875.

To all whom it may concern Be it known that I, THOMAS B. KIRKWOOD, ofBentonville, in the county of Fayette and State of Indiana, haveinvented a new and Improved Corn-Marker, of which the following is aspecification:

In the accompanying drawing, Figure 1 represents a vertical longitudinalsection on the line 0 c, Fig. 2, of my improved cornmarker, and Fig. 2 atop view of the same.

Similar letters of reference indicate correspondin g parts.

The invention will first be described in connection with drawing, andthen pointed out in the claim.

In the drawing, A represents the cutter carrying main board, that isconnected by hinged arms or beams B with the axle O of a cultivator orwalking corn-plow. The cutterboard A swings by arms B on the axle O, andmay be raised or lowered and supported in raised position by rings a andhook-arms!) of the tongue of the cultivator for turning around and goingto and from the field. The board A carries at its under side the cuttersD, of which three or more may be arranged according to the number offurrows to be made. The shovels D are centrally slotted and seated overthe cutter, being riveted at the upper part to the upward-bent cutterends. The cutter prevents the point of the shovels from catching onroots or stones in marking 011' the furrows. The drivers seat is placedon the top of a central upright, E, attached by strong braces to themain board A, the guide-marking pole F being pivoted to the upright E,

and capable to he swung to either side of the main board A withoutnecessitating the 'detaching of the pole when the guide-marking board isto be used at the opposite side. Double-guide braces G are applied toeach end of the main board to keep the guidemarking pole in place. Acutter-board, F, with symmetrically-arranged cutters F, is fastened tothe end of the guide-marker, at either side of the furrower, in hard ormellow ground.. The guide-marking board is, on the turning of thefurrower, swung with great facility to the opposite side, and forms thusa very convenient and quickly-adjusted guidemarking device. The furrowermay also be used without the walking-plow, by being detached from theaxleconnecting arms or beams, to be then attached to a tongue, formingthus a neat and handy furrowing and guide-markin g implement.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The branched cutters D, turned up, as shown, toform standards, in combination with slotted shovels D and board A, asand for the purpose set forth.

2. The combination, with pivoted frame A B, having cutters D, of theupright E, the pivoted pole F, the guide-braces G, and the boards F,having cutters F, as and for the purpose specified.
